AThas started rolling out a new update to LG V20 units on its network. Carrying a build number of NRD90M, the update brings Android security fixes for the month of December.

Although the official change-log isn't yet available, the update doesn't seem to bring along anything else. The Android version stays at 7.0 as well.
Other major US carriers, including Verizon and Sprint, have already rolled out the December security update to LG V20 units on their network.
